_________________ Night gathers, and now my watch begins.I am the sword in the darkness, I am the watcher on the walls, I am the fire that burns against the cold, the light that brings the dawn, the horn that wakes the sleepers, the shield that guards the realm of men. I pledge my life and honor to the knight's watch for this night and all the nights to come.
